Hi Stephen, it won't take that long if Nanosolar, mentioned by Terry in an earlier post, delivers as they seem poised to do since they have secured 100 million dollars of financing and are going into production in 2007, cf: http://www.nanosolar.com/articles.htm
What they seem to have achieved in pre-production is awesome: durable and efficient inexpensive nano-ink printed aluminum foil PV panels which could pay for themselves in just a few months at standard electricity rates! Potentially the definitive answer to the world's energy problems if an inexpensive storage technology emerges too (supercaps, hydrogen?), and maybe even if it doesn't since peak electricity consumption is in daytime.
